Main Uses

  A-171 is suitable for all kinds of complex shapes, all densities of polyethylene and copolymers. It is suitable for larger processing tolerance, filling composite materials, etc. It has high service temperature, excellent pressure cracking resistance, memory, wear resistance and impact resistance.

  It has the function of both coupling agent and crosslinking agent. The suitable polymer types are polyethylene, polypropylene, unsaturated polyester, etc. It can also be used to improve the affinity between glass fiber, inorganic filler and vinyl resin. It is commonly used in silane crosslinked polyethylene cables and pipes.
